1、maven配置:
maven对docker的支持插件有两种版本
**最新版本:dockerfile-maven-plugin**
```
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>${docker.plugin.version}</version>
</plugin>
```
**老版本:docker-maven-plugin**
```
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>${docker.plugin.version}</version>
</plugin>
```
我们使用新版本。
我们在maven中定义参数:
> docker.registry.url 参数是我们要发布镜像的 image id 前缀
> docker.registry.host 参数是我们要发布镜像的私服地址

2、在maven pom文件 build --> plugins 节点,对要发布的应用进行如下配置
```
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>${docker.plugin.version}</version>
<executions>
<execution>
<id>tag-latest</id>
<phase>deploy</phase>
<goals>
<goal>build</goal>
<goal>tag</goal>
<goal>push</goal>
</goals>
<configuration>
<tag>latest</tag>
</configuration>
</execution>
<execution>
<id>tag-version</id>
<phase>deploy</phase>
<goals>
<goal>build</goal>
<goal>tag</goal>
<goal>push</goal>
</goals>
<configuration>
<tag>${project.version}</tag>
</configuration>
</execution>
</executions>
<configuration>
<contextDirectory>${project.basedir}</contextDirectory>
<useMavenSettingsForAuth>true</useMavenSettingsForAuth>
<repository>${docker.registry.url}/blade/${project.artifactId}</repository>
<tag>${project.version}</tag>
<buildArgs>
<JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
</buildArgs>
</configuration>
</plugin>
```
3、在maven的setting.xml文件中增加私服镜像发布账号信息(如果私服不允许匿名发布的话)
在 标签servers下增加:
```
<server>
<id>register.docker.beree.net</id>
<username>账户名</username>
<password>密码</password>
<configuration>
<email>邮箱</email>
</configuration>
</server>
```
到此项目中maven的配置就结束了,接下来我们配置 Dockerfile 文件。
